  Provided is a liquid crystal display element that can be baked at a low temperature when forming a liquid crystal alignment film capable of imparting an alignment regulating property and a pretilt angle developing property via a photoalignment method. Further provided is a liquid crystal display element in which the liquid crystal pretilt angles are highly stable, and display burn-in hardly occurs even due to long usage. Further provided are a vertical liquid crystal alignment film to be used in the liquid crystal display element, and a liquid crystal aligning agent with which it is possible to provide the vertical liquid crystal alignment film. A liquid crystal aligning agent of the present invention contains: component (A), which is a polymer including (A-1) a site having an isocyanate group and/or a blocked isocyanate group and (A-2) a site having photoreactivity; component (B), which is a compound having, in a molecule, at least two functional groups of at least one type selected from the group consisting of an amino group and a hydroxyl group; and an organic solvent.

  本发明提供了一种液晶显示元件，该元件在形成液晶对准膜时可在低温下烘烤，通过光对准方法赋予对准调节特性和预倾斜角显影特性。本发明还提供了一种液晶显示元件，其液晶前倾角高度稳定，即使长时间使用也几乎不会出现显示烧损。还提供了一种用于液晶显示元件的垂直液晶对准膜，以及一种可提供垂直液晶对准膜的液晶对准剂。本发明的液晶对准剂包含：成分（A），即聚合物，包括（A-1）具有异氰酸酯基团和/或封端异氰酸酯基团的位点和（A-2）具有光活性的位点；成分（B），即化合物，在分子中具有至少两种官能团，其中至少一种官能团选自氨基和羟基组成的组；以及有机溶剂。
